Seems snappy compression is not enabled in your env.
By default Kylin leverages snappy compression to compress the output of MR jobs, as well as hbase table storage, to reduce the storage overhead. We do not choose LZO compression in Kylin because hadoop venders tend to not include LZO in their distributions due to license(GPL) issues. If you compression related issues happened in your cubing job, you have two options: 1. Disable compression 2. Choose other compression algorithms like LZO. Compression settings only take effect after restarting Kylin server instance (by `./kylin.sh start` and `./kylin.sh stop`). To disable compressing MR jobs you need to modify $KYLIN_HOME/conf/kylin_job_conf.xml by removing all configuration entries related to compression(Just grep the keyword "compress"). To disable compressing hbase tables you need to open $KYLIN_HOME/conf/kylin.properties and remove the line starting with kylin.hbase.default.compression.codec. -- Regards, *Bin Mahone | 马洪宾* Apache Kylin: http://kylin.io Github: https://github.com/binmahone
